FLOOD-GATE.

SPECIFICATION forming part of Letters Patent No. 300,102, dated June 10,1884.

(No model.)

' To all whom it may concern.-

Be it known thatl, JAMES M. llIE'lCALF, of Enfield, White county,Illinois, have invented a new and Improved Flood-Gate, of which thefollowing is a full, clear, and exact description.

My invention consists in the construction and arrangement of parts, aswill be hereinafter'fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure l is a perspective View of my improved flood-gate, and Fig. 2 isa plan view.

In a frame consisting of four posts, a, and suitable connecting-timbers,b c, and braces (1, setup by planting the posts in the ground, framingthem into mud-sills, or attaching them to a bed-frame or floor, e, asmay be preferred, I hang a pair of gates, f, to the posts a of theupstream side of the frame, so as to swing downstream and close togetherin an acute angle, as shown. I connect a weighted cord, 9, with eachgate, working over a sheave, 71, mounted over the upstream posts a, orany other suitable part of the frame, so that the weights i, attached tosaid cords, will rise and allow the gate to open whenever the pressureof the flood against the gates overbalances their gravity, and saidweights will close the gates whenever the'flood subsides 5 and I attacha check cord or chain, j, to each gate, to stop them at the propermeeting-point and prevent one from closing within the other. I

hinge the gates to the upper sides of the posts a, so that the pressureof the gates on the hinges is will be toward the posts, by which thehinges will'be better protected from the stress of the floods than ifconnected to the lower side, and I connect said hinges to the gates by acleat, Z, which enables the gates to be swung wide open withoutoverstraining the hinges, as would otherwise be the case in consequenceof the gates bearing against the insides of the posts before completelyopening.

.The gates will stand sufficiently above the bed of the stream orbed-floor eto allow the ordinary flow of water to escape under them whenclosed. Preferably the cords or chains 9 andj will be attached to postsk, extending upward from the gates.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, in a flood-gate, of thesupporting-frame consisting of posts a, connecting-timbers b c, andbraces d, gates f, weights and cords t g, and check cords or chains j,substantially as described.

2. In combination with the rectangular frame-work, the gates f, havingvertical cleats l, and the end hinges, 7:, said hinges being secured tothe upstream sides of the posts of the frame and to the faces of thecleats next to the sides of the frame-work, as described.
